can occur only when the nodes coincide with the period of the Full Moon,
which is generally twice, never more than three times in a year. If we
had started about four days before the occurrence of a Lunar eclipse, we
should travel all the time in the dark. This would have been obnoxious
for many reasons."

"One, for instance?"

"An evident one is that, though at the present moment we are moving
through a vacuum, our Projectile, steeped in the solar rays, revels in
their light and heat. Hence great saving in gas, an important point in
our household economy."

In effect, the solar rays, tempered by no genial medium like our
atmosphere, soon began to glare and glow with such intensity, that the
Projectile under their influence, felt like suddenly passing from winter
to summer. Between the Moon overhead and the Sun beneath it was actually
inundated with fiery rays.

"One feels good here," cried the Captain, rubbing his hands.

"A little too good," cried Ardan. "It's already like a hot-house. With a

twenty-four hours. I hope in heaven the walls of our Projectile won't

"Don't be alarmed, dear friend," observed Barbican, quietly. "The
Projectile has seen the worst as far as heat is concerned; when tearing
through the atmosphere, she endured a temperature with which what she is
liable to at present stands no comparison. In fact, I should not be
